STATEN ISLAND, N.Y. -- A 25-year-old woman accused just last week of dealing in prescription pills now faces charges she used forged prescriptions to score 720 doses of anti-anxiety medication.

Geri L. Castellano, who was already facing charges in a half-dozen criminal cases ranging from petty theft to drunken driving to drug dealing, was arrested Wednesday morning, after her alleged forgery scheme was exposed by a state Health Department investigator.

Ms. Castellano, who lives on Elwood Avenue in New Springville, is accused of forging seven prescriptions for the anti-anxiety drug alprazolam under the name of Dr. Nkanga Nkanga of Dongan Hills to herself and two other names between Nov. 10 of last year and Sept. 12 of this year.

She went to three different pharmacies, and managed to get six of the seven prescriptions filled successfully, amounting to a total 720 pills, court papers allege.

Dr. Nkanga told authorities he never wrote out any of the prescriptions, court papers allege.

Just a week prior to her arrest, police spotted Ms. Castellano pouring pills into the hands of Baudin Cenobafto, 22, of the 700 block of Klondike Avenue in New Springville, while the two were at the corner of Ferndale and Saxon avenues, also in New Springville, a law enforcement source said.

Ms. Castellano was arrested on charges of fifth-degree criminal sale of a controlled substance and seventh-degree criminal possession of a controlled substance in connection with that incident.

Cenobafto — who also has several criminal cases pending against him, including a Sept. 2 arrest in connection with an alleged mugging behind the New Springville Barnes & Noble — was charged with seventh-degree criminal possession of a controlled substance.

Ms. Castellano's latest arrests brings 35 new felonies and misdemeanor charges, including multiple counts of second-degree possession of a forged instrument, according to information from District Attorney Daniel Donovan's office.
